Abstract (en)
[origin: EP2039958A1] [Problems] To provide a seismic isolation device, even if a relative height between friction plates, which are laminated in a hollow part of a laminated rubber body, and the laminated rubber body changes at a deformation of the laminated rubber body, which prevents allophone, vibration and shock from inside of the seismic isolation device (laminated rubber body), resulting superiority in durability, safety, and amenity. [Means for Solving Problems] The seismic isolation device comprising: a laminated rubber body 2 in which elastic material layers 2b and rigid material layers 2c are vertically laminated one after the other; a plurality of friction plates 3 vertically laminated so as to be horizontally slidable and wholly enclosed in a hollow part 2a vertically penetrating the laminated rubber body; pressurizing means 4A, 4B arranged at a topmost portion and/or at a lowermost portion of the laminated friction plates and vertically adding pressure; and a friction reducing means 5 arranged between each outer peripheral portion of the plurality of the friction plates and an inner peripheral surface of the hollow part of the laminated rubber body. Even if a relative height of the friction plates and the inner peripheral surface of the hollow part of the laminated rubber changes, the friction reducing means smoothens the slide between them.
